Unfortunately, relational data management systems are not efficient enough to handle the on-line signal processing task in a monitoring system. The main current in research into database management system model for the needs of monitoring systems is connected with a data stream model. However, these systems are non-deterministic. This paper presents the developed methods of data stream processing for signal processing tasks in medical database management systems, as well asthe developed theorems of data sequences (stream) algebra with formal proofs. A direct link between some introduced operators and Beatty and Fraenkel theorems has been proved.  \n1. Introduction  \nThe currently available data management systems process data on the basis of relation calculus methods. This data processing method makes it possible to describe any objects (Entities) and the connection between them (Relation) . The method of describing data structures by means of Entity-Relationship Diagrams [1] has become a binding standard in the design of data management system structures.  \nA data management system can be separated in typical data processing systems. The application of a relational database management system in the systems that feed data from external sources (e.g. a monitoring system) was not efficient enough [2] . The search for active or sequential database extensions [3] broadened the scope of knowledge in this field, but did not solve the problem. The established relational paradigm makes it difficult to increase efficiency [1] .  \nThe current scientific effort to create a data stream management system model for monitoring systems is connected with a data stream model and data management systems [4] . The application of such a system in a monitoring task will allow simple and elegant notations of algorithms. Moreover, owing to a simple system construction data processing will become much more efficient.  \n*[E-mail address](E-mail address: michal@widera.int.pl)[: michal@widera.int.pl](E-mail address: michal@widera.int.pl)  \nPobrane z czasopisma Annales AI-Informatica [http://ai.annales.umcs.pl](http://ai.annales.umcs.pl)  \n[Data: 11/07/2026 20:52:36](Data: 11/07/2026 20:52:36)  \n Deterministic method of data sequence processing 315  \nThe main difference between the relational and stream systems lies in continuous queries [5] . By a continuous query we understand a query the realization plan of which is locked in an infinite loop. In a relational system, such a functionality is obtained by a relatively complicated and less effective method of continuous querying data (data base querying) by application or using several trigger sets. In a relational system, the data are introduced and approved by the user, on the other hand, in a stream system, the data are introduced from external, usually autonomic subsystems. Additionally, the data stream is infinite by nature. Traditional data management systems usually use data for which the maximum limit of resources has been estimated. Therefore, the use of infinite data sets requires the modification of some operators.  \n1.1. Data management systems  \nMedical monitoring systems record, analyze and present on-line information provided by medical devices [6] . The aim of research was to draw up a data management system and a query language that would enable forming and realization of signal processing tasks.
